Abstract: A composition comprises an ethylene oxide polymer and a water-soluble additive having the formula <FORM:0998353/C3/1> wherein R1 contains from 5 to 24 carbon atoms and is alkyl substituted or unsubstituted cycloaliphatic, heterocyclic or aryl group, X is H, alkyl, cycloalkyl, heterocyclic or aryl containing 1-24 carbon atoms; a is 1 or 2; Y is oxygen or a urethane group when a is 1 and nitrogen when a is 2; (n) is an integer from 2 to 60, and (m) is 1, 2 or 3.  The radicals R include phenyl, phenylene, alkyl-, aryl- or alkaryl-substituted phenyl and phenylene, and analogous derivatives of naphthyl, anthryl, and phenanthyl groups, benzyl, cyclohexyl, cyclohexylene, alkyl cyclohexyl and cyclohexylene, cycloheptyl, cycloheptylene, alkyl cycloheptyl and cycloheptylene, pyrrolidinyl, pyrrolidinylene, piperidyl, piperylidene, pyrrolyl, pyrolylene, pyridyl, and pyridylene.  Radicals X include hydrogen, methyl, ethyl, propyl, butyl, phenyl, alkylphenyl, arylphenyl, naphthyl, alkylnaphthyl, anthyl, phenanthyl, alkylphenanthyl, benzyl, cyclohexyl, alkylcyclohexyl, cycloheptyl, piperidyl or pyridyl. Specified additives include: nonylphenyl ethers of polyglycols having 2 to 60 oxyethylene units, cyclohexyl ethers of polyethylene glycol having 2 to 60 oxyethylene units, a -naphthyl ether of polyethylene glycol having 2 to 60 oxyethylene units, tris-(hydroxyphenyl) propane-ethylene oxide adducts with three chains averaging 2.96 oxyethylene groups per chain, p,p1 - diaminodiphenyl - methane - ethylene oxide addjucts with an average of 1.92 oxyethylene units per chain, 2,4-toluenediamineethylene oxide adducts having 4 chains averaging 3.1 oxyethylene units per chain, o-tolyl diethanolamine-ethylene oxide adducts with 2 chains averaging 1 oxyethylene unit per chain, phenylinocyanate-polyethylene glycol adducts and isopropanoltoluenediisocyanate polyethylene glycol adducts.  The concentration of the additive should be from 1 to 50% by weight based on the weight of polymer.  The ethylene oxide polymers include the water-soluble ethylene oxide homopolymers and copolymers comprising at least 90% by weight of ethylene oxide and less than 10% by weight of a lower olefin oxide, such as propylene oxide or butylene oxide.  In a comparison of the stress properties of films made from ethylene oxide polymers, the following plasticizers are used:  (23) glycol triacetate; (24) diethylene glycol diacetate; (25) triethylene glycol di-2-ethyl butyrate; (26) triethyl citrate; (27) glycerol; (28) hexanetriol; (29) 2-ethyl-1,3-hexanediol; (30) icosanol + 13 moles of ethylene oxide; (31) di-2-ethyl hexylamine + 20 moles ethylene oxide; (32) di-2-ethylhexylamine + 23 moles ethylene oxide; (33) triethylnonanol + 6 moles ethylene oxide; (34) butanol-butylene oxide-ethylene oxide adduct (butanol chained out with 18 moles of butylene oxide and then further chained out with 48 moles of ethylene oxide); (35) dipentaerythritol chained out with ethylene oxide (dipentaerythritol chained out with a mixture of 75% ethylene oxide and 25% propylene oxide to a molecular weight of 24,000); (36) nonylphenol + 4 moles propylene oxide.
